Operation device, electronic book device and electronic apparatus

An operation device for use by an operator, comprising:

• an operated body movable relative to a housing to slide in first and second directions;
• an operation signal producing part that responds to the sliding movement of the operated body by presenting tactile information through the operated body;
• and
• a rotatable touch member received in the operated body and having at least one protrusion permanently fixed to the touch member,
• wherein the touch member is rotated by the operation signal producing part to cause the at least one protrusion to contact the operator, and
• wherein a travelling direction of the touch member being changeable in accordance with a sliding direction of the operated body.

An electronic book device comprising:

• a display;
• a memory that stores book data to be displayed on the display;
• an operation device instructing flipping of pages of the book data;
• and
• a processor controlling the display, the memory and the operation device, the operation device including:
• an operated body swingably supported in a first direction and a second direction focusing on a swing axis that is operated at the time of flipping of pages;
• an operation signal producing part that produces an operation signal based on flipping of pages on the operated body;
• and
• a tactile information presenting part that presents tactile information through the operated body, the tactile information being based on flipping of pages,
• wherein the tactile information presenting part comprises a first touch member, a second touch member, a first driver, and a second driver,
• the first touch member and the second touch member being provided in the operated body,
• the first driver that drives the first touch member to protrude partially from a surface of the operated body through an opening formed in the operated body so as to bring the first touch member into contact with an object that operates the operated body when the operated body is swung in the first direction by the object, and
• the second driver that drives the second touch member to protrude partially from the surface of the operated body through an opening formed in the operated body so as to bring the second touch member into contact with the object when the operated body is swung in the second direction by the object.

An electronic device comprising:

• a processor;
• and
• an operation device connected to the processor, the operation device including:
• an operated body swingably supported in a first direction and a second direction focusing on a swing axis,
• an operation signal producing part that produces an operation signal based on an operation on the operated body, the operation signal being sent to the processor;
• and
• a tactile information presenting part that presents tactile information through the operated body under the control of the processor,
• wherein the tactile information presenting part comprises a first touch member, a second touch member, a first driver, and a second driver,
• the first touch member and the second touch member being provided in the operated body,
• the first driver that drives the first touch member to protrude partially from a surface of the operated body through an opening formed in the operated body so as to bring the first touch member into contact with an object that operates the operated body when the operated body is swung in the first direction by the object, and
• the second driver that drives the second touch member to protrude partially from the surface of the operated body through an opening formed in the operated body so as to bring the second touch member into contact with the object when the operated body is swung in the second direction by the object.
